Kitchen Extensions Parsons Green

Among the houses of Parsons Green, a kitchen extension is almost always a terrace job. The VOA list puts 32% of homes here in terraced houses and only 1% in semi-detached or detached ones, and the streets near the green are Victorian terraces. That points to a side return infill or a short single-storey addition behind the closet wing, a steel carried into old solid brick, and new drainage beneath the floor, with the new kitchen fitted in the same run of work.

In Parsons Green, a rear kitchen extension of about 30 square metres typically costs £45,000 to £97,500 excluding VAT, or £60,000 to £100,000 for a side return (indicative London ranges, Resi, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Parsons Green: the structural engineer we appoint designs the foundations and steel, we build the room and fit the kitchen, and a registered electrician certifies the electrics.

What shape of kitchen extension suits a Parsons Green terrace

On a terrace with a closet wing, the extra kitchen space normally comes from the side return, the strip of yard running beside the wing, sometimes wrapped round the back of the wing as well. Filling that strip turns a galley kitchen and a dark passage into one wide room facing the garden. With 32% of homes in the area terraced and only 1% semi-detached or detached, the wide rear and wraparound additions seen on semis are rare here. The design work goes into light, levels and the wall shared with next door.

Flats are the other side of the picture: 67% of homes in Parsons Green are flats, and the householder permitted development rules for extensions apply to houses only, not to flats and maisonettes. A ground floor flat owner wanting to push the kitchen into the garden therefore needs full planning permission, and usually the freeholder's consent under the lease as well. We build to whatever consent and drawings you hold.

Housing in Parsons Green

Take the 8,080 or so homes the valuation list gives Parsons Green: 67% flats, 33% houses, 68% from before 1919, 7% interwar and 24% post-war. Where most homes are flats, only a ground floor flat in Parsons Green with its own garden can extend its kitchen.

Permitted development limits and the Parsons Green Article 4 directions

Permitted development can cover a single-storey rear kitchen extension on a terraced house, but only within set limits. Under the national rules it cannot project more than three metres beyond the original rear wall of a house that is not detached, rising to six metres through the prior approval route where the land is not Article 2(3) designated land. Height is capped at four metres. Any side extension on designated land, such as a conservation area, needs householder planning permission.

Parsons Green has its own layer on top. The Parsons Green Conservation Area is Article 2(3) land, so a side infill inside it needs an application. The council's list of property-specific Article 4 directions also includes Parsons Green (1), Parsons Green (2) and Parsons Green (3), and a direction of this kind can take away rights a house would otherwise have. Before any drawing is fixed, ask the planning department whether your full address falls under one of them, because the answer decides whether a householder application is the first step.

Steel, foundations and drainage inspections on an SW6 kitchen build

The structural part of a side return scheme in Parsons Green is removing the old rear and side walls and carrying the house above on steel. If the work goes in under a Building Notice, a set of structural calculations has to be submitted for all structural work on an extension. The structural engineer we appoint produces them before the first wall comes out. The steel sizes, padstones and connections on site then follow those calculations exactly.

Where Hammersmith and Fulham is the building control body, its listed inspection stages include commencement, foundation excavations, covering of foundations, damp proof course and membrane, and backfilling drain excavations. Most visits need 1 day's notice, but drainage and completion inspections need 5 days' notice. On a terrace where the new gully and soil connection run under the kitchen floor, we book the drainage visit well ahead so the trench is not left open waiting for an inspector.

Flood risk, glazing and fitting the kitchen in one programme

Two thirds of the borough is within a flood risk zone, and where your kitchen extension needs a planning application, Hammersmith and Fulham asks for a flood risk assessment with it for a property in one. For a Parsons Green kitchen that steps down into the garden, the assessment can shape floor levels, the threshold to the patio and where the new drainage is routed. Knowing the zone for your street before the design is fixed saves a redraw later on.

Once the shell is watertight, the roof glazing and rear doors go in, then the kitchen itself. Planning the units, extraction route, sockets and plumbing positions alongside the structure means the first fix is placed where the cabinets will actually sit, and the plaster, floor and fitted kitchen follow on without a second contractor arriving to undo work. You deal with one programme and one point of contact from strip out to worktops.
